The Sable Heraldry is a example of the Raven Guard's inclination towards stealth tactics and guerrilla warfare. They adorn their jet black armour with symbols of the black bird that is their namesake.
- The Ravenclaw: Commonly placed on the right shoulder of veteran Raven Guard Battle-Brothers, the black Ravenclaw is painted upon a white shoulder pad and is reserved for those with long and venerated service to their Chapter. These Battle-Brothers are practiced in the art of guerrilla warfare; they react fluidly to changes on the battlefield and are constantly aware of the their surroundings.
- Raven Calvaria: Taking the form of a bird's skull, the Calvaria is a decoration worn by many Battle-Brothers across the Chapter. It is commonly worn hanging from a chain around Space Marine’s neck or strung from their right shoulder pad.
